Application filed September 2'?, 1916. Serial No. 122,512.

To all lw/Lom 'it may concern.'

Be it known thatwe, l oi-IAN VALFRID Osr- MAN and Qrmrms B. `loonwils,both of the city of l/Vinnipeg, in the Province of Manitoba, Canada,have `iointly invented certain new and useful improvements Vin Vindow-Screens, of which the following is the speciiication.

The invention relates to improvements in window screens and theprincipal object of the invention is to provide a screen which can beinserted in the window frame and attached to the sash and will open andclose with the sash when the same is raised and lowered.

A further object of the invention is to oonstruct and arrange a rollerscreen so that it can be manufactured at small cost, can `be readilyapplied on the various forms of eX- isting windows and when applied ispositive in action and effectively excludes insects and iies.

A still further objectof the invention is to construct and arrange aroller screen such that it is weather proof and does not require to beremoved unless desired in the winter time.

With the above objects in View the invention consists essentially in thearrangement and construction of parts hereinafter more particularlydescribed and later pointed out in the appended claims, reference beinghad to the accompanying drawing in which Figure 1 represents an exteriorview of the device as applied on a window7 parts being broken away toexpose construction.

Fig..2 represents a vertical Sectional view through the screen and lowerportion of the window frame sash with the Sash closed.

Fig. 3 represents a vertical sectional View of a portion of the frameand sash with the screen open.

Fig. 4t represents a horizontal sectional view through the window frameand sash and looking downwardly toward the sill.

Fig. 5 represents an enlarged detailed vertical sectional view throughthe right hand end of the roller showing the method of fastening thespring.

Fig. 6 represents an end view of the roller.

Fig. 7 represents an enlarged detailed horizontal sectional view throughthe parting strip.

Fig. 8 represents a face view ofthe right hand spring strip.

Fig. 9 represents an enlarged detailed vertical sectional view throughthe perforated edging strip applied on the screen.

In the drawing like characters of refere ence indicate correspondingparts in the several figures.

1 represents a window frame of ordinary construction comprising sidemembers 2 and 3 erected on the sill t, the side members embodyingupright facing boards 5 and 6 and inserted intervening boards 7, theinner edges of the facing boards being positioned so that they extendbeyond the inserted boards and form the outer guides 8 and 9 for thewindow sashes.

Parting stripe 1() and 11 are located centrally between the guides 8 and9 being car-` ried by the board 7 of the side members of the frame. A

All of these parts are of ordinary construction and as our invention isattached to the f posing spring .Strips or hangers 13 and ll which havetheir upper ends permanently fastened by screws 15 to the frame and havetheir lower ends bent slightly inwardly and provided, one with a slotshown at 16 andv the other with a rounded hole 17, the slot and holebeing horizontally opposite. rlhe frame is notched away at 19 behind thehanger 13 to allow the same to be pressed in when it is desired, toremove the roller later described. ylhe two hangers carry the springroller 2O which is constructed and arranged as now described.

One end of the roller is supplied with an extending pin or stub axle 21which is received within the opening 17 and the other end thereof iscored out as shown at 22 and Contains a coiled spring 23 spiraled arounda spindle Qt which has the inner end thereof rotatably mounted in acarrying plate 25 secured to the roller and the outer end thereofflattened as indicated at 26 and protruding through a cap plate 27permanently secured to the end of the roller.

A collar 28 is provided on the spindle to prevent it from shifting tothe right and the inner end of the spring is fastened to .ingvit will beobvious that when the roller is turned in oneV direction the spring willbe tightened or coiled with the result that when the roller is releasedit Vwill return back tothe koriginal position, the spring uncoiling. I

To the roller we secure the inner end of `a strip of wire netting29which is approximately the full width of the frame and has the upperedge thereof fitted with lan edg- .Yng strip 30 supplied at suitablerintervals with perforations 31 by means of which the edge of the stripcan be fastened to the lowermost cross member 12 of the sash by f meansof hooks 32 supplied .on the cross weather proof we have provided ahousing member.

In order to accommodate the roller of the screen the lower ends of theparting strips are cut short of the sill as shown at 33 and the innerfaces of both of the parting strips Y are longitudinally grooved orchanneled at 34 to receive the edges of the screen which, it will beunderstood, extendy beyond the edging strip and into thegrooves.

In order' to render the roller screen or casing 35 on the sill and aguard 3G on y'the sash which coperate when the sash is closed toentirely inclose the roller screen. The casing is actually a strip ofsheet metal passing the full width of the frame and havinggthe loweredge flanged and fastened at 37 to the sill, the body portionk thereofslightly rounded to conform to the roller and the upper edge terminatingin a position such that it will pass behind the edge f of the guard 36when the sash is closed.

from the above description it will be seen that thisdevice can bereadilv applied on the various types of existing window frames Y andwhenapphed can remain as a ixture as when closed the casing and guardeffectively protect the screen against the weather. It can however, bereadily taken out by removing the guard and then pressing in the springhanger 13 to release the roller. Once the roller is taken out the edgingstrip can be raised from the hook and the complete screen stored tillrequired for further use.

What we claim as our invention is 1. The combination with a window frameand a sash vertically slidable in the frame, of a spring constrainedroller, offset spring straps suspending the roller from the frame in alocation adjacent the frame sill and a screen attached to and wound onthe roller and having the free end thereof secured to the sash.

2. The combination with a window frame and a sash vertically slidable inthe frame, of a spring constrained roller removably mounted in the lowerportion of the frame and adjacent the frame sill, a screen secured toand wound on the roller, means detachably fastening the free edge of thescreen to the lower part of the sash, and means detachably fastening theroller to the sash.

3. The combination with a window frame Y and a sash vertically slidablein the frame,

of a pair of oppositely disposed depressible hangers located on thesides of the frame kand adjacent the frame sill, a spring constrainedroller mounted in the hangers, a screen attached to and wound on theroller and extending between the sides of the frame and means removablyfastening the free edge of the screen to the lowermost portion of thesash, comprising a perforated edging strip carried by the screen andhooks on the sash co-acting with the perforations.

l. The combination with a window frame, a sash slidably mounted in theframe and a spring constrained roller screen carried by the frameadjacent the sill and attached to the sash and adapted to open and closein the raising and closing of the sash, of a housing secured to the silland passing between the side members of the frame and covering theroller screen and a guard carried by the sash and co-acting with thecasing in the closed position of the sash.

Signed at Winnipeg this 30th day of August, 1916.
